Document Summary
5/11: symbols: a form that represents something other than itself. Human language: physical substance stands in for substance that represents ideas: words represent ideas, categories, entities, phonemes: combinable elements that serve as substance of form, for spoken language: signal that serves as form half of symbol is. Sound: sounds are organized, segments: sections of particular acoustic signals, darkness: loudness (black- louder frequency, lighter- quieter, sound: a type of compression wave- energy transmitted thru some medium. Fluctuations in mass/density of medium: radiating from a source- some event that channels/directs energy, pulses, waves. Compression waves: ocean waves: mass of water moves (not on shore- current, sound: mass of air moves; energy moving thru air. Sound waves- a kind of compression waves: changes in air pressure. Loudness (size of wave relative to baseline) = amplitude; loudness. Source for sound waves: some event that channels/directs energy in such a way as to affect air pressure.
